Prior techniques for multiple arterial phase hepatic imaging require lower resolution and increased slice thickness combined with SENSE or keyhole imaging techniques to accelerate image acquisition. Modified-LAVA sequence enables fast abdominal MRI with high spatial and temporal resolution. Modified-LAVA supports a novel adaptive 2D centric view ordering, efficient sampling pattern with 2D auto-calibrated acceleration and partial Fourier acquisition to achieve faster scanning. Double arterial phase MRI can be performed with identical slice thickness, spatial resolution, and anatomic coverage as is used in single phase imaging. Multiple arterial phases simplify bolus timing and provide information to improve tumor detection and characterization.
